  • The composition and overall structure of high precise and high dynamic star simulator system is presented, and a new method is put forward based on sub-pixel display technology to improve the dynamic star simulator to display the star point more precisely, which can reduce the position deviations of both geometric center and the energy center of the star point. Meanwhile, a new method for fast and accurate retrieval of the navigational star in the entire celestial sphere is presented by partitioning the SAO (Smithsonian Astrophysical Observatory) star catalogue, analyzing the four elements of the spacecraft attitude to determine where the visual axis points to, eliminating the search and match of navigational stars far from the visual axis so as to reduce the search area, hence decreasing the time that the whole celestial stars traversal required. Through simulation testing, results show that the speed of this quick search method to select the celestial navigational star has been increased by nearly 10 times.
